How to Build an Ethernet Geiger–Müller Environmental Data Logger with W55RP20-EVB-PICO?

Project description

Summary This project uses the WIZnet W55RP20-EVB-PICO to build a fixed-site environmental monitoring node that measures Geiger–Müller pulse activity, temperature, and humidity. The W55RP20 runs the acquisition, storage, local dashboard, and remote-upload logic, while its integrated W5500 controller provides wired Ethernet and hardware TCP/IP processing for local and Internet-connected monitoring. What the Project Does The system converts radiation events from a Geiger–Müller tube into timestamped environmental records. A high-voltage circuit drives the tube, a conditioning stage converts…
